5% because 55% - 30% = 25% and 70 + 25 = 95% and the remainder is 5%
The new climate goal is to end most fossil fuel burning, thus, reducing climate-changing impacts. This is one of the options spelled out in a U.N. document that’s being negotiated<span>, which is expected to be finalized during end-of-year talks in Paris. We</span><span> could aggressively turn to cleaner energy supplies and efficiency projects so as to end the need to use fossil fuels. </span>We need to set a goal that requires an end to the growth in the amount of greenhouse gas pollution that’s added each year to the atmosphere. Another option <span>would be based on reaching carbon neutrality — a world in which we pump out less greenhouse gas pollution than we bury, such as by replanting forests, or perhaps through geoengineering projects.</span>
