The fact is, the large team of thousands of people who lead operations at Amazon have always cared deeply for our hourly employees, and we're proud of the work environment we've created. We're also proud of the fact that Amazon is a company that does more than just create jobs for computer scientists and people with advanced degrees. We create jobs for people who never got that advantage.
Despite what we've accomplished, it's clear to me that we need a better vision for our employees' success. We have always wanted to be Earth's Most Customer-Centric Company. We won't change that. It's what got us here. But I am committing us to an addition. We are going to be Earth's Best Employer and Earth's Safest Place to Work.
In my upcoming role as Executive Chair, I'm going to focus on new initiatives. I'm an inventor. It's what I enjoy the most and what I do best. It's where I create the most value. I'm excited to work alongside the large team of passionate people we have in Ops and help invent in this arena of Earth's Best Employer and Earth's Safest Place to Work. On the details, we at Amazon are always flexible, but on matters of vision we are stubborn and relentless. We have never failed when we set our minds to something, and we're not going to fail at this either.
We dive deep into safety issues. For example, about 40% of work-related injuries at Amazon are related to musculoskeletal disorders (MSDs), things like sprains or strains that can be caused by repetitive motions. MSDs are common in the type of work that we do and are more likely to occur during an employee's first six months. We need to invent solutions to reduce MSDs for new employees, many of whom might be working in a physical role for the first time.
One such program is WorkingWell -- which we launched to 859,000 employees at 350 sites across North America and Europe in 2020 -- where we coach small groups of employees on body mechanics, proactive wellness, and safety. In addition to reducing workplace injuries, these concepts have a positive impact on regular day-to-day activities outside work.
We're developing new automated staffing schedules that use sophisticated algorithms to rotate employees among jobs that use different muscle-tendon groups to decrease repetitive motion and help protect employees from MSD risks. This new technology is central to a job rotation program that we're rolling out throughout 2021.
Our increased attention to early MSD prevention is already achieving results. From 2019 to 2020, overall MSDs decreased by 32%, and MSDs resulting in time away from work decreased by more than half.
We employ 6,200 safety professionals at Amazon. They use the science of safety to solve complex problems and establish new industry best practices. In 2021, we'll invest more than $300 million into safety projects, including an initial $66 million to create technology that will help prevent collisions of forklifts and other types of industrial vehicles.
When we lead, others follow. Two and a half years ago, when we set a $15 minimum wage for our hourly employees, we did so because we wanted to lead on wages -- not just run with the pack -- and because we believed it was the right thing to do. A recent paper by economists at the University of California-Berkeley and Brandeis University analyzed the impact of our decision to raise our minimum starting pay to $15 per hour. Their assessment reflects what we've heard from employees, their families, and the communities they live in.
Our increase in starting wage boosted local economies across the country by benefiting not only our own employees but also other workers in the same community. The study showed that our pay raise resulted in a 4.7% increase in the average hourly wage among other employers in the same labor market.
And we're not done leading. If we want to be Earth's Best Employer, we shouldn't settle for 94% of employees saying they would recommend Amazon to a friend as a place to work. We have to aim for 100%. And we'll do that by continuing to lead on wages, on benefits, on upskilling opportunities, and in other ways that we will figure out over time.
If any shareowners are concerned that Earth's Best Employer and Earth's Safest Place to Work might dilute our focus on Earth's Most Customer-Centric Company, let me set your mind at ease. Think of it this way. If we can operate two businesses as different as consumer ecommerce and AWS, and do both at the highest level, we can certainly do the same with these two vision statements. In fact, I'm confident they will reinforce each other.
The Climate Pledge
In an earlier draft of this letter, I started this section with arguments and examples designed to demonstrate that human-induced climate change is real. But, bluntly, I think we can stop saying that now. You don't have to say that photosynthesis is real, or make the case that gravity is real, or that water boils at 100 degrees Celsius at sea level. These things are simply true, as is the reality of climate change.
Not long ago, most people believed that it would be good to address climate change, but they also thought it would cost a lot and would threaten jobs, competitiveness, and economic growth. We now know better. Smart action on climate change will not only stop bad things from happening, it will also make our economy more efficient, help drive technological change, and reduce risks. Combined, these can lead to more and better jobs, healthier and happier children, more productive workers, and a more prosperous future. This doesn't mean it will be easy. It won't be. The coming decade will be decisive. The economy in 2030 will need to be vastly different from what it is today, and Amazon plans to be at the heart of the change. We launched The Climate Pledge together with Global Optimism in September 2019 because we wanted to help drive this positive revolution. We need to be part of a growing team of corporations that understand the imperatives and the opportunities of the 21st century.
Now, less than two years later, 53 companies representing almost every sector of the economy have signed The Climate Pledge. Signatories such as Best Buy, IBM, Infosys, Mercedes-Benz, Microsoft, Siemens, and Verizon have committed to achieve net-zero carbon in their worldwide businesses by 2040, 10 years ahead of the Paris Agreement. The Pledge also requires them to measure and report greenhouse gas emissions on a regular basis; implement decarbonization strategies through real business changes and innovations; and neutralize any remaining emissions with additional, quantifiable, real, permanent, and socially beneficial offsets. Credible, quality offsets are precious, and we should reserve them to compensate for economic activities where low-carbon alternatives don't exist.
The Climate Pledge signatories are making meaningful, tangible, and ambitious commitments. Uber has a goal of operating as a zero-emission platform in Canada, Europe, and the U.S. by 2030, and Henkel plans to source 100% of the electricity it uses for production from renewable sources. Amazon is making progress toward our own goal of 100% renewable energy by 2025, five years ahead of our initial 2030 target. Amazon is the largest corporate buyer of renewable energy in the world. We have 62 utility-scale wind and solar projects and 125 solar rooftops on fulfillment and sort centers around the globe. These projects have the capacity to generate over 6.9 gigawatts and deliver more than 20 million megawatt-hours of energy annually.
Transportation is a major component of Amazon's business operations and the toughest part of our plan to meet net-zero carbon by 2040. To help rapidly accelerate the market for electric vehicle technology, and to help all companies transition to greener technologies, we invested more than $1 billion in Rivian -- and ordered 100,000 electric delivery vans from the company. We've also partnered with Mahindra in India and Mercedes-Benz in Europe. These custom electric delivery vehicles from Rivian are already operational, and they first hit the road in Los Angeles this past February. Ten thousand new vehicles will be on the road as early as next year, and all 100,000 vehicles will be on the road by 2030 -- saving millions of metric tons of carbon. A big reason we want companies to join The Climate Pledge is to signal to the marketplace that businesses should start inventing and developing new technologies that signatories need to make good on the Pledge. Our purchase of 100,000 Rivian electric vans is a perfect example.
To further accelerate investment in new technologies needed to build a zero-carbon economy, we introduced the Climate Pledge Fund last June. The investment program started with $2 billion to invest in visionary companies that aim to facilitate the transition to a low-carbon economy. Amazon has already announced investments in CarbonCure Technologies, Pachama, Redwood Materials, Rivian, Turntide Technologies, ZeroAvia, and Infinium -- and these are just some of the innovative companies we hope will build the zero-carbon economy of the future.
I have also personally allocated $10 billion to provide grants to help catalyze the systemic change we will need in the coming decade. We'll be supporting leading scientists, activists, NGOs, environmental justice organizations, and others working to fight climate change and protect the natural world. Late last year, I made my first round of grants to 16 organizations working on innovative and needle-moving solutions. It's going to take collective action from big companies, small companies, nation states, global organizations, and individuals, and I'm excited to be part of this journey and optimistic that humanity can come together to solve this challenge.
Differentiation is Survival and the Universe Wants You to be Typical
This is my last annual shareholder letter as the CEO of Amazon, and I have one last thing of utmost importance I feel compelled to teach. I hope all Amazonians take it to heart.
