What is a climate solution, what is not, and why?

Everyone’s talking about climate solutions. But what exactly makes something a climate solution? Who figures out if it’s truly a solution, and how?

In this Drawdown Ignite presentation, Senior Scientist for the Built Environment Amanda D. Smith, Ph.D., explained how Project Drawdown evaluates technologies and practices that have the potential to be global climate solutions. She also introduced the evidence-based framework we have developed to identify proven climate solutions and quantify their potential for turning the tide on climate change and gave a sneak peek of what to expect when Project Drawdown releases our new climate solutions resources next year.

Top Takeaways:

  1. Climate solutions must first and foremost materially reduce the concentration of greenhouse gases and other warming agents – carbon dioxide, methane, nitrous oxide, fluorinated gases, black carbon – in the atmosphere.
  2. Project Drawdown defines global climate solutions as identifiable technologies or practices that:
    • materially reduce the concentration of greenhouse gases in the atmosphere by cutting emissions at the source or removing them from the atmosphere by supporting carbon sinks
    • are readily available today and have a proven ability to reduce greenhouse gases 
    • reduce greenhouse gases on the global scale necessary to actually impact climate change.
  3. Anything that claims to be a solution cannot: 
    • be technologies that are currently unproven and unavailable  
    • increase emissions elsewhere or shift them to a different sector so that the result of adopting the solution is no longer a net reduction in emissions 
    • make the world a worse place by increasing inequity and environmental harm
    • accelerate another planetary crisis, such as water loss, pollution, or biodiversity loss.

We aren’t addressing climate change because we like a certain global mean temperature. We’re doing it to build a safe and equitable world where people and a diverse community of other species are thriving.

  1. Climate solutions that reduce greenhouse gases today are better than those that promise reductions at some undefined point in the future.
  2. There is no single solution or sector that alone can stop climate change – we need a tapestry of solutions working in concert to create a better, more sustainable future. 
  3. Project Drawdown uses the best available science and evidence to assess the most promising climate solutions. 
  4. Project Drawdown is creating the Drawdown Explorer, a new climate solutions resource launching in 2025 that will empower you to identify:
    • where a particular solution is most impactful
    • when the solution should be implemented compared to others to maximize greenhouse gas reductions
    • how to overcome barriers to the implementation of the solution
    • who is positioned to help accelerate the adoption of the solution and what they can do. 
  5. For each solution in the Drawdown Explorer, researchers at Project Drawdown have evaluated the best available data on the solution’s: effectiveness; cost; current adoption level; potential adoption level; benefits for people, the environment, and biodiversity; and risks and trade-offs. 
  6. All Drawdown Explorer solutions are reviewed by internal and external scientific experts to ensure accuracy and rigor.
  7. The Drawdown Explorer will be simple, action-oriented, and transparent, allowing anyone and everyone to use it to implement solutions, whether you’re a policymaker, educator, philanthropist, business leader, or individual looking to create change.

Greenwashing and denial won’t solve beef’s enormous climate problems

I’ll admit it: I like beef. Like many Americans, I was brought up to believe that beef was a central part of a traditional family meal. My mom made it. My kids ate it. Marketing campaigns told me it was healthy. Everywhere I went, I saw Americans eating lots of it. And for many years, I didn’t question these choices.
