Jenson Button won the 2009 drivers' championship by 11 points from Red Bull driver Sebastian Vettel
Formula 1's points scoring system will be changed next season under a new scheme proposed by the sport's bosses.
At the moment, the top eight finishers earn 10, eight, six, five, four, three, two and one point respectively.
The new proposal will see the winner take 25 points, 20 for second place, 15 for coming third and then 10, eight, six, five, three, two and one points.
The World Motor Sport Council agreed to introduce the new system to reflect the expansion from 10 to 13 teams.
The plan to change the scoring system came from the FIA's F1 Commission, which is made up of key stakeholders from the teams, promoters, suppliers and sponsors, and chaired by president Bernie Ecclestone.
Last season Ecclestone tried to introduce a medals system, with the championship being decided by race victories rather than cumulative points, but the idea was shelved after receiving an unenthusiastic reception.
Under the medals system Felipe Massa would have beaten Lewis Hamilton to the 2008 world championship, but the Brazilian said it was not the correct way to decide the title.
The 2010 season will feature 13 teams, three more than in recent seasons.
For that reason, the governing body agreed to award the top 10 finishers points and change the points system for the first time since 2003.
World champion Jenson Button gave his support to the scheme, saying: It's a great idea. It's nice that you get five points over second for winning.
"That's important because we all love winning races. I won six races this year and I got just two more points."
A strong mandate has also been given to the Sporting Working Group, a sub-committee of the F1 Commission made up of the FIA and F1 teams, to develop detailed proposals to improve the show which will take effect from next year.
