After years of agreements and plans to limit global warming, we are still way off track.
This is one of the fundamental conclusions of a recent report released by the United Nations’ Intergovernmental Panel on Climate Change (IPCC), the world’s most authoritative body for climate science. The report, formally called the Synthesis Report of the Sixth Assessment, shows that the last decade’s emissions have reached the highest level in human history. It was almost ten years ago that the IPCC finalized its report. This rapid pace of warming is unprecedented in the last 2,000 years and probably longer, making it difficult for us, plants and animals to adapt.
These are terrifying discoveries. And as one of his lead authors in the Sixth Assessment Report series, I urge you, and many others, to keep up with the severity of the climate crisis until the next report or disaster puts the climate back on track. We recognize that people may raise their arms to stop it. in the news cycle.
But here’s what I want you to know. we still have hope. His fellow IPCC authors and I have spent years combing through the evidence and have learned that in all areas of life there is something we can do now. This is the short-term target we need to stay on track to limit global warming to 1.5 degrees Celsius, the global target outlined in the Paris Agreement, and scientifically, the climate It has been identified as a key threshold to avoid the worst effects of variability. climate change.Many of these solutions not only result in cleaner air and more jobs, but also help governments, businesses, and consumer.
“We already know the big thing the world has to do to address climate change: reduce our use of fossil fuels and use renewable energy sources like wind and solar to power our homes and buildings. It is about decarbonizing our energy system by providing electricity – electrifying wherever possible – vehicles, heating systems, appliances, machinery, etc. We will also improve public transport and reduce the use of cement, plastic, We need to limit industrial-scale emissions that occur when producing materials such as steel, move to more sustainable food systems, protect and restore forests and other ecosystems.”
We detailed all these necessary solutions in the IPCC Mitigation Report published last year as part of this Sixth Assessment Cycle. For that to happen, those who run governments and create policies and economic incentives will need to work together to drive the widespread adoption needed to cut emissions in half over the next seven years. As an example, the U.S. government passed landmark legislation last year that provides new funding for a significant expansion of renewable energy in our power grids, transportation systems and homes. With this increase, US emissions are projected to drop 40% from 2005 levels by 2030. This is a big step, but much more is needed in the United States and around the world.
How can we expect change on such a large scale and pervasive when our world seems more divided than ever? , innovations, and behavioral changes can increase your chances of success. Here, I want to dig into what these behavioral changes that could reduce emissions by 40-70% mean for you and me.
For the first time since IPCC assessments began in 1990, mitigation reports devote a chapter to assessing the socio-cultural aspects of climate change mitigation. Our decisions as professionals such as investors, architects, teachers, restaurateurs, builders, urban and transport planners, farmers, procurement managers, engineers, influencers and community leaders .
The most meaningful lifestyle changes include low-emission transport choices (walking, biking, using public transport, switching to electric vehicles where possible, limiting air travel where possible). increase. Our mobility choices have the greatest potential to reduce our carbon footprint and can also clean our air, especially in the United States, where transportation is currently the largest source of emissions.
Finally, we can use energy efficient materials, appliances and technology when building or remodeling homes and buildings. As part of the Inflation Reduction Act, all American homeowners now have access to financial incentives such as heat pumps and electric cookstoves that reduce both emissions and electricity bills.
But there are hurdles to widespread adoption of these lifestyle changes. And those hurdles may be different or harder for different people. How can you choose a cleaner transportation option if you don’t have the infrastructure to support it? How can you buy more efficient appliances if your stores don’t have them in stock? Personally, I try not to take more than necessary. But as a mom here in America, I find it really hard to avoid over-consumption when everything for kids seems designed to be used once and then thrown away.
Experts and decision makers in the transportation, building and food industries to make this low carbon lifestyle affordable and practical for the average consumer and make these transitions accessible to everyone. should help prioritize these products.
Home to more than half of the world’s population and emitting two-thirds of global GHG emissions, cities are a critical region for change. What if all architects and developers building new homes and apartments used sustainable materials? Certain fully electric and energy efficient heating, appliances and lighting. Have you added green roofs and perennial gardens and installed electric vehicle charging stations in every parking space? What would happen if we designed the city to be closer to the center of our work and protected 30% of the city’s existing natural spaces from development to lock in greenhouse gas uptake? What if we created healthier, more sustainable menus that used less …? What if cities helped the people who build office buildings, schools, and restaurants, including composting infrastructure? What if all business procurement managers chose only energy-efficient and sustainable materials, products and services? and revisions to school district standards can help encourage these decisions.
If you want to see these options made available in a way that works for you, this is where you can and need to raise a concern about a project not being done in your community.
The IPCC’s Synthesis Report is more than five warnings. It clearly shows that worse climate impacts are still around the corner, with a detailed set of solutions for government and industry leaders to avoid them. But this report highlights the fact that every decision can make a difference. We have a role to play, not only as consumers and citizens, but also as investors, influencers and professionals. The longer it takes for the world to accept these solutions, the more difficult the final road will be. And the sooner we wake up to the climate crisis unfolding around us, the sooner people and nature will benefit from a cleaner, safer and more stable future.
