The point
You shouldn’t have to choose between doing what’s right for the environment and what’s good for the economy.
And with a balanced energy approach, you don’t have to.

RNG and Power-to-Gas:
Be on the right side of history
The timing is right to blend in RNG without creating price shock with consumers
Get ahead of it—California is a bellwether state
why invest?

Our industry needs to takedefinitive steps
Robust monitoring and timely fixing of leaks. No excuses.
Shift our thinking from risk mitigation to proactive environmental stewardship.
Invest in RNG and look into ways to decarbonize the energy system.
